Hello!

First time poster. My wife and I purchased a home in Southern Wisconsin with a pond last summer. The previous owners explained that we "just run the pumps when we want the waterfall on" which led to a summer and fall of fighting mass amounts of string algae. I've since found this to be incorrect. So this year I vowed to do it the right way, clean it, and try to keep it nice.

Our pond isn't a large one. It is a 7ft long by 5ft wide triangle that has an average depth of 2ft. It's probably <300 gallons total. We have a 350GPH fountain pump (Tetra FK5) as well as a two tiered waterfall supplied by a 4500GPH Aquascape pump in a skimmer basket. The only current inhabitant of the pond is a water lily in a bucket, though we would like a couple goldfish if possible. I attached a photo below.

After cleaning the pond Friday and starting both pumps I ran into an issue. I would have to keep adding water to the skimmer box for the waterfall as every few hours (1-2) the pump would begin to starve. After closer inspection, there was a stone affixed partially blocking the skimmer. After removing this, it flowed much better, but it still lost water level over the course of 8-10 hours. I have turned the waterfall off since Sunday evening. Since then, the pond has not lost any water, and neither has the lower waterfall bucket (the upper bucket back drains into the lower bucket when I shut off the pump). I guess my question is, is this normal? Do you need to keep adding water to the waterfall for the first few days until things are saturated (filter mats, lavarocks)? If not, what would you suggest? There doesn't seem to be a leak in the pond itself, or in the piping to at least the lower waterfall bucket. Anything you recommend would be helpful. Thanks for your time.

How much water? Does your waterfall splash a lot? You could be losing a little water from it hitting the rocks and then evaporating.

I'd say somewhere between 5-8 gallons over the course of 8hrs. The falls do splash some, but it didn't seem like a lot to me. There's also a spot on the falls where the water pools a bit as well.

That pump may be way to big for a skimmer in a 300 gallon pond
That's what I thought too when I saw the GPH on it. Maybe I need to take some measurements and figure out the actual pump size required for the waterfall.

Do you know the manufacturer of the skimmer? What is the width of the skimmer weir opening?
Initial reaction.....you have a leak!
I thought I had a leak too on my first reaction, but with the waterfall off the pond holds steady as well as the first (lower) waterfall bucket. The other (upper) waterfall bucket drains back through the lower bucket when I shut the pond off.

I'll get dimensions on the skimmer opening tonight.

Most times when a pond is losing water....it's somewhere in the waterfall.
This has been my experience. With my pond, Its always a portion of the falls that settled and allowed water to slowly leak, or plants growing over the liner edge of the falls forcing the edge down and water leaking there, or rocks holding the edge down and water leaking.

BTW, Lovely pond! You will enjoy it.

Thanks everyone. I have it running right now with just the fountain pump. It's honestly cleaner than its ever been. I know there are some low spots in the falls where water pools, that may be the first spot I start to look.

The skimmer is 6".

I ran the falls tonight and there was definitely a stream of water going around rocks and outside the falls. There is no waterfall foam around the rocks bordering the falls. There is a liner under the falls. Should I clear the rocks and reassemble them with foam?

Welcome to our group!

You mean there is liner under the water that is flowing around the rocks bordering the falls? or the water is running totally out of the pond into the ground.

There is a liner under the water that is flowing around the rocks. I tracked the stream to where it seemed to flow back into the pond. However, it's quite a bit, and it actually pools under the rocks, in some spots a good 2-3 inches deep.
